Science Technology
systematized
It is the ability or the capacity to do work.
Energy
What is the SI unit for mass?
Kilogram (kg)
It is the simple push or pull.
Force
It is involving the gathering of information and data about the natural world using our senses or specialized scientific tools.
Observation
It is referring to the application of scientific knowledge.
Technology
The branch of Physics that studies about Light.
Optics
1 Newton (N) is equivalent to =
1 kg.m/s2
What is the SI unit for force?
Newton (N)
The variable in an experiment that is changed or manipulated by the scientist.
Independent Variable
True or False: Learning about the sound, knowing its principle is an example of technology.
False - Learning sound is Science
Branch of Physics that deals on the study of motion.
Mechanics
The measure of the force of gravity pulling on the object.
Weight
True or False: Force is a vector quantity.
True
A scientist studies how the amount of fertilizer affects the number of tomatoes a plant produces. What is the independent variable, and what is the dependent variable?
Number of Tomatoes - dependent Variable
Amount of Fertilizer - independent Variable
True or False: Technology is simply the practical application of scientific knowledge; therefore, a scientific discovery must always happen before a new technology can be invented.
False: You must realize that the relationship is a two-way street: while science often leads to technology, historical technologies (like the steam engine) were frequently invented by trial and error before scientists fully understood the thermodynamics behind why they worked.
Who is considered to be the father of Mechanics?
Isaac Newton
True or False: Mass on earth will the same mass on the surface of the moon
False
The sum of all the forces acting on an object.
Net Force
Hypothesis
Describe the difference between a science and Technology.
Science is the knowledge, while technology is the application scientific knowledge.
The branch of Physics that deals on the study of sound.
Acoustics
An astronaut travels from Earth to the Moon. How do their mass and weight change? Explain your answer.
The mass will remain the same but the weight will decrease.
A block is placed on a table. A student pushes it to the right with a force of 10 N, while friction resists the motion to the left with a force of 3 N. What is the net force acting on the block?
7 N - to the right
True or False: The scientific method is a rigid, linear, step-by-step sequence that scientists must always follow in exact order—from observation to hypothesis, experiment, and conclusion—to validate their research. Support your answer.
False: it is not a linear process but a cyclic process.
